McKayla Maroney and her "Fierce Five" U.S. women's gymnastics teammates appeared on the Late Show with David Letterman Tuesday night, where the host had them show off their best "McKayla Maroney is not impressed" faces.

"It is pretty funny," said Maroney, 16, of the meme that's taken over the web. "After I did it, the girls kept pointing it out, 'You're doing that face again.'"
